Yes, MS has it in Office (http://msdn.microsoft.com/en-us/library/microsoft.office.core.msotristate.aspx) - but there are five (!) values in it, but values other than True / Flase are not supported.

I thinkt the state "msoTriStateMixed" is explainable: It will be returned when you have a group of checkboxes of mixed state - in that case the state of the group is neither true nor false.
msoTriStateToggle could be the currently selected checkbox etc.
But why msoCTrue?

TRWTF is that both "False" and "More False" have the same ID...? I confess to not having a particularly strong grasp on the intentions of the developers involved here -- it's going to need a debrief session and a code review. And I think an earlier-than-scheduled career appraisal is in order as well.

Is it then possible to assign a complement operation upon an ExtraBoolean such that the complement of e.g. Seriously Doubtful is Probably True? Or does one need to posit the existence of statements whose extra-boolean truthiness and falsitude are in fact independent? e.g. a statement may be Most False but at the same time Possibly True? We could build an entire field of mathematics upon this concept. Perhaps model a statement's Extra-booleanity on the complex plane: truthiness along the real axis and falsitude along the complex. Then a statement that is purely Political Statement, when multiplied by the negative square root of minus one becomes a Religious Conviction?

Might this analysis be used to get to the bottom of the relationship between US and UK during the early 2000's?

BASIC has done not-equals with <> more or less from the beginning. And it isn't the only language that uses <> for not-equals - consider the Pascal family of languages - and overall, giving the chronology of programming languages, that makes != a strange way of expressing <>, and both of them a strange way of expressing .NE..

TRWTF is Big Bang Theory's popularity.
It just gets boring after a few episodes and the characters are all so very cliché.
How in the world did it manage to stick around for so long?

It always amuses me that, on these forums, you come across so many people who assume that if they like something then everybody MUST like it, and that if they don't like something then everybody else MUST hate it too. No arguments.

He's right though, it really is shit.

Captcha: luctus. Looks like we luctus out and this article's comments didn't go to discourse.

I agree, those are rather strange ways of expressing northeast. I would have gone with ↗.

I like it. And as you know, my opinion is the only one that really counts. You may try and deny it, but it is an existential truth of reality.

so what you're saying is that the dislike is not true, or false, but there might be a third state after all....
